Gearcase Lubrication - Husqvarna HUV4420-D Owner's Manual

GEARCASE LUBRICATION

NOTE: Dispose of used oil according to the environmental laws and regulations for your area.
LUBRICATION LEVEL CHECK FOR FRONT DIFFERENTIAL, TRANSMISSION, AND
REAR DIFFERENTIAL
Each gearcase component is equipped with two oil port plugs (1 and 2) (Figure 28, Figure 29, and
Figure 30). When the vehicle is on a level surface, use the level indicator hole (upper plug) (1) as a lubricant
level indicator. Lubricant level should be even with the bottom of level indicator hole (1).
LUBRICATION CHANGE FOR FRONT DIFFERENTIAL, TRANSMISSION, AND REAR
DIFFERENTIAL
Use the lower plug (2) for drainage (Figure 28, Figure 29, or Figure 30). Remove both plugs to allow the
lubricant to drain faster. See preceding NOTE.
Front differential:
Clean and install the drain plug (2) and washer before filling the front differential with new lubricant
(Figure 28). Tighten the drain plug to 11 ft-lb (14.9 N·m). Use a funnel when filling the gearcase through the
lubricant level indicator hole (1). See Periodic Lubrication Schedule on page 32. Tighten the level indicator
plug to 10 ft-lb (13.6 N·m).
Transmission:
Clean and install the drain plug (2) before filling the transmission with new lubricant (Figure 29). Tighten the
drain plug to 8 ft-lb (10.8 N·m). Use a funnel when filling the transmission through the lubricant level indicator
hole (1). See Periodic Lubrication Schedule on page 32. Apply Loctite 567 to the threads of the level indi-
cator plug and tighten the plug to 21.0 ft-lb (28.5 N·m).
